ion-CREAM DIPPER.

"To all whom may concern;

' Be it known that I, EDWIN WALKER, a

for the purpose of removing cream, or a similar substance, from a receptacle and discharging the same into a plate, or other container, the

. operations of dipping and of releasing and discharging the contents of the dipper being easily and quickly performed by one hand.

2"O" new implement consists principally of a cup shaped container and means adapted to turn within said container for the purpose of overcoming the adhesion of the material to the walls of the container. Preferably, this releasing device is arranged to rotate within the container, andin one formof the invention said device is in the form of a skeleton scraper, the members of which lie close to the inner surface of the container.

My implement is provided with means for operating the scraper bythe hand which grasps the handle or stock of the dipper. In one form of construction said operating -means isa' lever fulcrumed on the handle, and a rack pivoted to the lever, said rack begeared to the scraper. With the operatmg devices is eombineda spring adapted to return the scraper to, or to maintain it in, one position, but this spring will yieldor Ito giveto the pressure applied to the lever for the operation of the parts in order to free the cream from the container.'

A designates'a suitable shank or frame adapted to carry the several working parts of t 1e implement. As shown, this frame A is bent or inclined at a point intermediate of its length, as at a, and one end of said frame is rovided with a suitable handle a.

designates a container for the cream or other substance which is to be measured and dispensed by my im lement. This container is shown in the orm of a cup, closed at its small end, and open at its large end, the on being, preferably, conical; but it will be LlIlt erstood that the cup may be made in an suitable shape and size. is ormed at one end to rovide a seat a for the reception of the smal end of the cup, the latter being made in a separate piece from The frame A the frame and secured by an suitable means to the seat portion a thereo It is my prac tice to make the cup B from a single piece of sheet metal, and toattach the same to an end portion of the frame A; but the method of making the cup and the material therefor,

are not essential parts of this invention, be-

cause the cup maybe made in one piece with the frame if desired.

It is Wellunderstood by those familiar with this art that in dispensing ice cream and.

other frozen or cold substances, there is a tendency of the substance to adhere to the walls of the container or cup 13. In order to readily dischar e the substance from the cup I have rovided means'for scraping, cutting, or ot erwise releasing the oontents from engagement with the walls of the cup. In one form of my invention said means is represented as a scraper C, the same consisting of two members 0, c, and a cross member 0. The scraper is made by stamping or cutting the, same froma sin le strip or length of metal of the required 11111: ness, and t the interior shape ofthe cup B, as clearly shown by Fig; 2. The members 0 of the scraper lie close to and in contact with the inner surface of the cup, while the member 0 of said scraper fits snugly to the closed bottom of said cup.

The scraper C is adapted to rotate within the cup. B for the purpose of making the scraper members -"c sweep around the interior of the our), and for the purpose of in). )arting this rotary motion to san scra er, have rovided means located exterior y of the cup or operating the scraper. Preferably, the

\ operating means are carried by the frame A,

s scraper is bent to conform to so that pressure may be applied to one member of said 0 crating means by the hand which grasps t e handle a, thus enabling the implement to be operated in dipping and measuring the cream, and the scraper is turned within the dipper cup, so as to release the substance and facilitate the discharge thereof from said cup.

I will now proceed to describe a preferred form of the scraper operating means. I

The shaft D is secured to the end )ortion c of the scraper, said shaft extending tlirough the closed end of the cup, so as to-be journaled in said end and in a guide E on the frame A, see Figs. 2 and I. On the exposed end of the shaft D is a gear pinion F, which lies within the guide .15]. With this pinion engages the rack teeth 9 of a slidable bar or rack G, the latter being disposed in compact relation to one side of the frame A, and extending lengthwise of the implement. rack is operated by a lever H, which is fulcrumecl in a' slotted portion i ofthe frame A. The lever H. is of angular form, and at one end said lever has a thumb or operating piece 7, while the other arm h of the lever is' slotted or forked to receive the bar or rack G,

whereby said bar or rack may be connected pivotally'at g to said arm h of the lever. The several operating parts of the scraper are held normally in one position by the ac tion of a spring I, the same being, preferably, coiled around the fulcrum pin of the lever II. One end of the spring is seated against the frame A, while the other end thereof acts on a stud or member "5', on the arm h of the lever. The thumb piece h of said lever is quite close to the handle a of the implement, so that said thumb piece may be operated by pressure of the thumb, and to prevent the thumb from slipping along the piece 71 I providethe pro ection h thereon. A guard Jfis made in one piece with the frame A, and lies close to the arm h of the lever, said guard operatin to prevent the hand from engaging with the lever.

' The guide E, heretofore mentioned, is made in one piece with, or suitably attached to, the frame A. The rack G is held in this guide, as shown by Fig. 4, so as to remain in engagement with the pinion F, the guide and the pinion being so disposed with relation to the rack as to keep the latter from having any idle or lost motion. The rack G is held in position by the pivotal connection 9 to the lever, and by the guide E.

I. find in practice that there is a tendency of the scraper and the shaft 1) to separate or break, owing to the resistance offered by the frozen cream to the movement of the scraper Within the cup, and to the strain which consequently takes place on the connection between said scraper and the shaft D. In order to strengthen the joint b tween these arts I ma resort to a number of ex e- This dients, two of which are shown by Figs. 5 and 6. In Fig. 5, the shaft D is provided with a shoulder 12 and with a head (1. The shouldered part (1 passes throughan opening in the cross piece 0 of the scraper, and on this part (1 is fitted a reinforcing-plate or washer D, the latter being secured to the cross piece a of said scraper in any suitable way. The reinforcement D has its end portions doubled or folded around the cross piece 0, as indicated at d The plate D is attached to the scraper and to the shaft, so as to increase the metal at the point between said scraper and shaft, thereby materially strengthening the joint.

In Fig. 6 the cross piece 0 is shown as having the metal bent or -flanged around the opening, so as to produce an eyelet 0 This bent edge or eyelet of the scraper engages with and is fastened in a suitable way to, the shouldered part (1 of the shaft, thus increasing the strength of the joint. I prefer, however, to employ the construction shown in Fig. 5, but it will be understood that my invention is not restricted to any particular means for strengthening the joint betweenthe scraperand its shaft, because this detail may be modified by a skilled mechanic.

In using my implement it is held by-one hand grasping the handle a, and to dip the cream from the freezer or other receptacle, the cup B is forced into the substance so as to fill said cup, and thereby measure the cream. After withdrawing the dipper from the receptacle, the operator presses on the thumb piece h, so as to move the lever against the tension of the spring, thereby imparting endwis'e movement to the rack G, which rotates the scraper through the medium of the pin ion F, and the shaft D. The members of the scraper are caused to travel or sweep the walls of the cup for the purpose of making the cream free from said cup, and by inverting the dipper, the cream or other contents of the cup is discharged into a plate or other receptacle. It will be seen that the operation of dipping, measuring and discharging the cream can all be performed by one hand,. thus leaving the other hand free to hold and manipulate the plate or other receptacle.

In my implement the devices for operating the scraper are arranged so as to be out of the way in dipping cream from a freezer,

said devices being on the opposite side of the I or stock which. is bent or offset, and to attach mass the cup to one end ofthe frame,- because the? bundle o 'and the. cup are so related as to balance the implement and thus allow it' to he used to the-best'advantage. As shown by Figs. 2 and 3,'th'e lever H has one arm slot-- te or forked for the accommodation of the spring, and said lever is fitted in a slotted part of the frame, thereby housing the spring I, and disposing the parts compactly, The projection-h revents the thumb from slipping fprevents' the fingers from being pinched between thelever: and'the frame, while also' affording a pressure surface for the handwhen'forcing the dipper into cream or other hard substance:
